Ethereum node as an API

First-time Đapps makers learn the hard way that downloading and syncing the Ethereum blockchain sucks. Infura builds blockchain infrastructure and provides API calls so you can develop and run your Đapps without hosting your own node. This literally will save you DAYS.

The Infura product is an essential part of the Ethereum ecosystem now. uPort uses the Infura infrastructure to handle our smartphone (https://play.google.com/store/apps/details?id=com.uportMobile) application's transaction requests

I've been tinkering with a similar idea for the last couple of years. I like your model of providing value to actual companies right now whilst thinking long-term about R&D and scalability. Looks awesome! Best of luck with everything.
